`iSpeciication forming part of LettersPatent N o. 115,378, dated May 30, 1871.

\ LJAMESD; STANLEY, of the'city and county of Baltimoreand State of Maryland, have ini `vented a new and approved Mode of Extract-Y i ing Tar from Pine Wood, leaving a residuum l charcoal, of which the followingis a specification: y y I i ,Natarcand Objectsof the Invention. My invention relates tothe extractin g: of tar from pine wood placed Within car-wagons in the interior of retorts by the action of heat i upon the tops and sides of the retorts, causing `the tar to drop through the open bottoms of the cars upon the cold,` surface of the retorts beneath,\the tarpassing therefrom uninterruptedly through suitable discharge-passages, all superfiuous gases and vapors ndin g egress through vapor-pipes rising from air-vessels forming connectionswith the said dischargepipes. i

`lhscmptton of the Brewing'.

Figure I is alongitudinal section .upon line G H of Fig. II of the combination embodying my invention. Fig. II is a vertical transverse section, showin g those "partsof the same which, upon Fig. I, are cut by the perpendicular and horizontal lines QD. i Fig. III represents halves of `a sectionaliplan of the samcupon the lines E F IyKof` Fig. II.

i General A A are two retorts,which may be of cast or wrought iron, .or any other suitable mate-` rial. They are built in masonry, `that part i. which is directly under them being intended y by its solidity to protect the bottom of the rel torts from lheatlthat `theymay present the cool \.surfacewrequired.` `The `retortsfare simultanej ously heated by ire in the furnace E, common `to both. Atrack is representedby e e, upon which the carsB B` areniade to travel.` That part of the track marked ff is separated from the retorts, and. may extend to any distance or direction. The cars are of' skeleton construction, to allow therebya circulation of heat among the wood placed within them anda free fall of the tar extracted. The front ends of the cars form air-tight covers to the openings in the retorts, and are fastened thereto by means of the brackets g g and the bar h.

Fire having been applied to the furnace E, the bars B B charged or filled with pine-wood sticks standing perpendicularly therein, and the retorts closed by the means before described, the lire and heat follow the courses indicated bythe arrows through fines 7c Z m to stack H. The resinous matter in the wood thus affected by heat is extracted, falls upon the cool bottoms of the retorts, and runs oii, without stoppage, through the discharge-pipes V c o. Air-chambers are represented by d d,

from which vapor-pipes n n rise, `joining to a single pipe leading to the stack H.

By this process yellow tar is produced, as distinguished from the ordinary black tar made by the usual method.

I claim asmy invention- 1. The combination of two retorts, A A, set

in masonry, with one furnace, E, common to both, substantially as and for hereinbefore set forth. Y

2. The combination of the said two retorts A Awith .skeleton cars B B upon tracks, substantially as and for the purposes hereinbefore setforth. 'y

3. The combination of the free dischargepipes c c and vapor-pipes n n, substantially as and for the purposes hereinbefore set forth.
